Answer: It is not enough evidence to support the researcher's claim.
Step-by-step explanation:
Since we have given that
n = 500
So, the hypothesis are as follows:
So, the z value would be
At α = 0.05
z= -1.64
So, 1.64<-1.33
So, we accept the null hypothesis.
Hence, it is not enough evidence to support the researcher's claim.
Answer:
Step-by-step explanation:
If angle C is the right angle, then side c is the hypotenuse.
Use Pythagoras' Theorem to find the length of side a:
Given:
- b = 2√22
- c = 13
<u>Tan Trig Ratio</u>
where:
is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
Given:
- O = side opposite angle A = a = 9
- A = side adjacent angle A = b = 2√22
